Portion Estimation – the next time you eat one serving do this. In this picture on top I tried my best to estimate one serving. 36g. The bottom is a measured serving by weight. 28g. In this case my estimation is off by 8g or 28%. Over the course of a day that turns a 2000 calorie diet to a 2560 calorie diet. Assuming that I was trying to lose a pound per week by cutting out 500 calories per day this means that on my “diet” I would be eating enough to GAIN a pound every 58 days or about half a pound a month
